Jasmine duplicates test cases to subsequent files

Expected Behavior

Test cases are just listed under the file they exist in

Actual Behavior

Test cases are also listed under all subsequent files

I think the issue might be some form of caching in here.

If I move the creation of the jasmine instance (Lines 115+116) inside the forEach, i.e. a new one for each file, the test cases only appear for the correct file.

• NTVS Version: 1.5.20902.1 Commit Hash:b474efcb6f92db52a8f8e2e6a8cb9648476885cc
• Visual Studio Version: 16.8.0 Preview 3.2
• Node.js Version: 10.15.0
• Jasmine: 3.6.1

Steps to Reproduce

1. Create a .netstandard project following https://docs.microsoft.com/en-us/visualstudio/javascript/unit-testing-javascript-with-visual-studio?view=vs-2019#unit-test-net-core-and-net-standard
2. Add 2 or more test files
3. Rebuild project

Start at Nodejs/Product/TestAdapter/TestFrameworks/Jasmine/jasmine.js around lines 115-126, where the Jasmine instance is created and files are processed. Reproduce with a .NET Standard project containing two or more test files, then verify that each test case appears only under its own file after rebuilding the project.
